4. To install a 2346 in a UCS 1000 or 1001 chassis, you must use a Model 1230 BAM; each BAM
can hold up to two 2346 modems. Follow these steps to install the BAM and the 2346:
a. Insert a BAM into an available slot in a UCS 1000 or 1001. Slide the BAM into the rails and
push it firmly into the backplane, then tighten the captive screws. If you encounter
resistance, check that no connector pins are bent.
b. Insert a 2346 into an unused slot in the BAM. Slide the 2346 into the rails and push it firmly
into the backplane, then tighten the captive screw. If you encounter resistance, check that no
connector pins are bent.
5. To install a 2346 directly in a UCS 1002 or standalone enclosure, insert the 2346 into an unused
slot. Slide the 2346 into the rails and push it firmly into the backplane, then tighten the captive
screw. If you encounter resistance, check that no connector pins are bent.
If you encounter more difficulty, contact Canoga Perkins at [phone] for technical assistance.
Note: The BAM and 2346 are hot-swappable and can be inserted or removed without disrupting
data transfer in other application modules.
6. If the 2346 is in a standalone enclosure, set the switch on the enclosure for loopback to Normal.
The 2346 uses electrical cables to connect to the local site and fiber optic cables to connect to the
remote modem. Follow these steps to connect the electrical and optical cables:
7. To connect to the local site, plug the BNC cables from the local equipment into the Rx and Tx
connectors using Tx to Rx, and Rx to Tx orientation.
Dirty optical connectors are a common source of link loss or attenuation problems, especially for
single mode fiber (SMF). Clean the connectors before plugging in a cable and whenever there is a
significant or unexplained light loss. To prevent contamination, always install protective dust covers
on unused fiber optic connectors.
8. Wipe the ferrule and the end-face surface of the male fiber coupler with a lint-free isopropyl
alcohol pad from a fiber cleaning kit.
9. Use canned air to blow out any dust from the female fiber coupler.
